This invention relates to a file which may be used advantageously fortrimming or filing a person's finger nails.

An object of the present invention is the provision of a file of theindicated character which embodies improved abrasive means whereby theflle is guided by the nail being filed, and whereby the abrasive meansfunctions effectually in moving in either direction as the file is beingreciprocated.

A further object of the invention is the provision of a file of theindicated character having novel means for conveniently and effectuallygripping and manipulating the file for the intended purposes.

A further object is the provision of a file whose abrasive meansconsists of teeth so formed and arranged as to easily file or trim thefinger nails with the desired rounded effect.

With the foregoing, other objects of the invention will appear when thefollowing specification is read in conjunction with the accompanyingdrawing, in which- Fig. 1 is a plan view of a file embodying thefeatures of the present invention.

Fig. 2 is an end view.

Fig. 3 is a side view.

Fig. 4 is an enlarged fragmentary plan view showing the abrasive meansof the file more clearly.

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4.

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 4.

The file is made from a steel plate which is cut and stamped before itis hardened to provide a body ID, a rudimentary abrasive means along onelongitudinal edge of the body, and means H on the body opposite theabrasive means for gripping and manipulating the file.

The rudimentary abrasive means stamped in the body 10 consists of aseries of diagonal concavities and corresponding intervening ridgesproviding teeth in the finished article. .The body having the aforesaidfeatures is then hardened according to known methods and the area having the rudimentary abrasive means also may be put through a temperingprocess.

The rudimentary abrasive means is finished by grinding the aforesaidridges with an emery wheel having a cross-sectionally convex periphcry.This operation produces a longitudinal groove in the body formed by aseries of equally spaced concave teeth 12 extending diagonally of thebody as shown. Each of the teeth l2 thus formed has two sharp curvedcutting edges l 3 extending diagonally of the body I. These teethconstitute the abrasive means of the file.

The means I I is more or less flexible due to the series of transversecuts in the body [0 extending through the edge providing a series oflateral members. The means I l enables a person to conveniently andsecurely grip the file and to manipulate or reciprocate it in carryingout the filing operation on the finger nails.

By reason of the diagonal arrangement of the teeth l2, the cutting edgesI3 thereof function effectually in moving in either direction as thefile is being reciprocated. The teeth l2 being concave withcorresponding cutting edges l3 provide a longitudinal groove whichreceives the edge of the finger nail to be filed or trimmed and guidesthe file with respect to said edge.

The means II applied to the body 10 obviously may be used as a comb.Also, the body 10 may be provided With a clip [4 to retain the articlein a pocket of a garment, a string cutter l5, nail scraper I 6, bottleopener I! and envelop opener I8.

I claim:

1. A finger nail file comprising a body made of relatively thin fiatmetal, said body having a groove extending along one longitudinal edgethereof, abrasive means on said body consisting of a series of parallelteeth in the groove extending diagonally thereof, and means on the bodyfor grippin and manipulating said file, said groove guiding the fingernail so as to be filed by the abrasive means upon the manipulation ofthe file.

2. A finger nail file comprising a body made of relatively thin fiatmetal, said body having a groove extending along one longitudinal edgethereof, abrasive means on said body consisting of a series of parallelconcaved teeth in the groove extending diagonally thereof, each of saidteeth having two cutting edges corresponding to the formation andarrangement of the teeth, and means on the body for gripping andmanipulating the file, said groove guiding the finger nail so as to befiled b the abrasive means upon the reciprocation of the file.
